Actually, I don't think the current system is really all that different from what you propose. A church wedding does come with the legal implications, but those are all filed separately. The church handles the religious aspects, while the legal aspects are handled by legal experts. Having a church ceremony is optional, since you can just as easily get a court wedding, free of any religious groups. The right wings extremists don't want gays and lesbians to even have a court wedding, because they wish to force their views on others, believing they are right, and everyone else is wrong, as freedom to marry is apparently a violation of their religious texts. All we do is make sure the bigots keep their views out of politics, and wait for them to die off; the hardliners just aren't going to change their views, no matter what the law says.
